Filling Gaps in the Microsporidian Tree: Rdna Phylogeny of Chytridiopsis Typographi (Microsporidia: Chytridiopsida)
Parasitology Research (2019) 118:169–180 https://doi.org/10.1007/s00436-018-6130-1 GENETICS, EVOLUTION, AND PHYLOGENY - ORIGINAL PAPER Filling gaps in the microsporidian tree: rDNA phylogeny of Chytridiopsis typographi (Microsporidia: Chytridiopsida) Daniele Corsaro1 & Claudia Wylezich2 & Danielle Venditti1 & Rolf Michel3 & Julia Walochnik4 & Rudolf Wegensteiner5 Received: 7 August 2018 /Accepted: 23 October 2018 /Published online: 12 November 2018 # Springer-Verlag GmbH Germany, part of Springer Nature 2018 Abstract Microsporidia are intracellular eukaryotic parasites of animals, characterized by unusual morphological and genetic features. They can be divided in three main groups, the classical microsporidians presenting all the features of the phylum and two putative primitive groups, the chytridiopsids and metchnikovellids. Microsporidia originated from microsporidia-like organisms belong- ing to a lineage of chytrid-like endoparasites basal or sister to the Fungi. Genetic and genomic data are available for all members, except chytridiopsids. Herein, we filled this gap by obtaining the rDNA sequence (SSU-ITS-partial LSU) of Chytridiopsis typographi (Chytridiopsida), a parasite of bark beetles. Our rDNA molecular phylogenies indicate that Chytridiopsis branches earlier than metchnikovellids, commonly thought ancestral, forming the more basal lineage of the Microsporidia. Furthermore, our structural analyses showed that only classical microsporidians present 16S-like SSU rRNA and 5.8S/LSU rRNA gene fusion, whereas the standard eukaryote rRNA gene structure, although slightly reduced, is still preserved in the primitive microsporidians, including 18S-like SSU rRNA with conserved core helices, and ITS2-like separating 5.8S from LSU. Overall, our results are consistent with the scenario of an evolution from microsporidia-like rozellids to microsporidians, however suggesting for metchnikovellids a derived position, probably related to marine transition and adaptation to hyperparasitism. -

Secreted Proteins in Microsporidian Parasites: a Functional and Evolutionary Perspective on Host-Parasite Interactions
Secreted proteins in microsporidian parasites: a functional and evolutionary perspective on host-parasite interactions.

Signature ……………………………………. Page| 1 Abstract The Microsporidia form a phylum of obligate intracellular parasites known to cause disease in humans and a diverse range of economically important animal species. Once classified as ‘primitive’ eukaryotes, it is now recognised that the peculiarities of microsporidian genomics and cell biology are, in fact, the consequence of extreme reduction allowed by an intimate relationship with the host cell. Excluding survival as an extracellular spore, microsporidia are in direct contact with the host throughout their developmental lifecycle, from entry to egress. Host cell manipulations have been described in morphological terms, but despite this, characterisation of such processes at the molecular level remains challenging. The logistics of the microsporidian lifecycle suggest secreted proteins and membrane proteins with extracellular domains may be involved in virulence and implicated in host cell manipulation. This study employs bioinformatic tools to predict secreted proteins in diverse microsporidia and comparative genomics to identify conserved proteins which may be required for host cell manipulation, pathogenicity and lifecycle progression. -
Alternatives in Molecular Diagnostics of Encephalitozoon and Enterocytozoon Infections
Journal of Fungi Review Alternatives in Molecular Diagnostics of Encephalitozoon and Enterocytozoon Infections Alexandra Valenˇcáková * and Monika Suˇcik Department of Biology and Genetics, University of Veterinary Medicine and Pharmacy, Komenského 73, 04181 Košice, Slovakia; [email protected] * Correspondence: [email protected] Received: 15 June 2020; Accepted: 20 July 2020; Published: 22 July 2020 Abstract: Microsporidia are obligate intracellular pathogens that are currently considered to be most directly aligned with fungi. These fungal-related microbes cause infections in every major group of animals, both vertebrate and invertebrate, and more recently, because of AIDS, they have been identified as significant opportunistic parasites in man. The Microsporidia are ubiquitous parasites in the animal kingdom but, until recently, they have maintained relative anonymity because of the specialized nature of pathology researchers. Diagnosis of microsporidia infection from stool examination is possible and has replaced biopsy as the initial diagnostic procedure in many laboratories. These staining techniques can be difficult, however, due to the small size of the spores. The specific identification of microsporidian species has classically depended on ultrastructural examination. With the cloning of the rRNA genes from the human pathogenic microsporidia it has been possible to apply polymerase chain reaction (PCR) techniques for the diagnosis of microsporidial infection at the species and genotype level. The absence of genetic techniques for manipulating microsporidia and their complicated diagnosis hampered research. This study should provide basic insights into the development of diagnostics and the pitfalls of molecular identification of these ubiquitous intracellular pathogens that can be integrated into studies aimed at treating or controlling microsporidiosis.

9B Taxonomy to Genus
Fungus and Lichen Genera in the NEMF Database Taxonomic hierarchy: phyllum > class (-etes) > order (-ales) > family (-ceae) > genus. Total number of genera in the database: 526 Anamorphic fungi (see p. 4), which are disseminated by propagules not formed from cells where meiosis has occurred, are presently not grouped by class, order, etc. Most propagules can be referred to as "conidia," but some are derived from unspecialized vegetative mycelium. A significant number are correlated with fungal states that produce spores derived from cells where meiosis has, or is assumed to have, occurred. These are, where known, members of the ascomycetes or basidiomycetes. However, in many cases, they are still undescribed, unrecognized or poorly known. (Explanation paraphrased from "Dictionary of the Fungi, 9th Edition.") Principal authority for this taxonomy is the Dictionary of the Fungi and its online database, www.indexfungorum.org.

The Phylogeny of Plant and Animal Pathogens in the Ascomycota
Physiological and Molecular Plant Pathology (2001) 59, 165±187 doi:10.1006/pmpp.2001.0355, available online at http://www.idealibrary.com on MINI-REVIEW The phylogeny of plant and animal pathogens in the Ascomycota MARY L. BERBEE* Department of Botany, University of British Columbia, 6270 University Blvd, Vancouver, BC V6T 1Z4, Canada (Accepted for publication August 2001) What makes a fungus pathogenic? In this review, phylogenetic inference is used to speculate on the evolution of plant and animal pathogens in the fungal Phylum Ascomycota. A phylogeny is presented using 297 18S ribosomal DNA sequences from GenBank and it is shown that most known plant pathogens are concentrated in four classes in the Ascomycota. Animal pathogens are also concentrated, but in two ascomycete classes that contain few, if any, plant pathogens. Rather than appearing as a constant character of a class, the ability to cause disease in plants and animals was gained and lost repeatedly. The genes that code for some traits involved in pathogenicity or virulence have been cloned and characterized, and so the evolutionary relationships of a few of the genes for enzymes and toxins known to play roles in diseases were explored. In general, these genes are too narrowly distributed and too recent in origin to explain the broad patterns of origin of pathogens. Co-evolution could potentially be part of an explanation for phylogenetic patterns of pathogenesis. Robust phylogenies not only of the fungi, but also of host plants and animals are becoming available, allowing for critical analysis of the nature of co-evolutionary warfare. Host animals, particularly human hosts have had little obvious eect on fungal evolution and most cases of fungal disease in humans appear to represent an evolutionary dead end for the fungus. -

Carol I, No. 20A, 700505, Iaşi, Romania 2Department of Botany, Academy of Natural Sciences 1900 Benjamin Franklin Parkway, Philadelphia, PA 19103 USA * Correspondence to: [email protected] Abstract — Neolecta vitellina, one of the rarely collected ascomycete species in Europe, is reported from Romania for the first time. The species was found on the ground, under Norway spruce (Picea abies) in 2004, from the Nature Reserve “Tinovul Mare” Poiana Stampei (Eastern Carpathians, Romania). Subsequent field observations have confirmed the presence of Neolecta vitellina in the same location, in the period 2005–10. A description and photographs of the specimens are presented. Key words — Ascomycota, Neolectaceae, ITS sequence Introduction The genus Neolecta Speg. belongs to the ascomycete family Neolectaceae (Redhead 1977), order Neolectales (Landvik et al. 1993), class Neolectomycetes (Taphrinomycotina, Ascomycota). This genus includes three accepted species —N. flavovirescens Speg., N. irregularis (Peck) Korf & J.K. Rogers, N. vitellina— with clavate, unbranched to lobed yellow ascomata, up to about 7 cm tall (Landvik et al. 2003). Of these three species, only N. vitellina has been reported from Europe (Bresadola 1882, Geitler 1958, Hansen & Knudsen 2000: 48–50, Krieglsteiner 1993: 421, Landvik et al. 2003, Ohenoja 1975, Redhead 1989). Work published by European researchers about Neolecta vitellina refers mainly to phylogeny, morphology and ultrastructure (Landvik 1996, 1998; Landvik et al.
